2025年1月30日 · Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent processing into steel.

This article comprehensively discusses and elaborates the information regarding blast furnace, its construction details, including its main parts and their working phenomenon and function. This article also highlights the application of these furnaces for its practical use.

2021年10月20日 · The construction of a blast furnace is divided into 3 parts. Starting from the top the 3 parts are Top, Stack, and Hearth. The top consists of the feeder mechanism for the entry of ores.

The components of a blast furnace include the Charge, exhaust gas outlet, charging bells, gas outlet, tuyeres, taphole, bustle pipe, slag hole, refractory lining, and conveyor system. How Does Blast Furnace Works? A blast furnace is a large, hot …

Molten iron is produced in a blast furnace by the following steps: 1. Charge (solid iron ore, coke, and limestone) is constantly dumped into the top of the furnace. 2. A blast of hot air is blown into the furnace from the bottom. 3. Coke is the fuel that supplies additional heat, increasing the temperature of the charge. 4.

Fig. 6 shows the essential parts of a blast furnace for smelting iron. It is given the name of blast furnace because combustion is maintained by forcing a blast of air through the mass of fuel , ore and flux which completely fills the furnace.

2019年7月12日 · Blast Furnace and Process Description :- Iron blast furnace is a vertical shaft, which is used to melt the iron ore and to produce hot metal by heat exchange and chemical reaction. The burden charge consisting of iron oxide, flux and coke and it provides through the throat from the top of the furnace.

2020年3月3日 · The raw materials of the blast furnace are (i) solids (ore, coke, flux) which are charged from the top of the furnace and (ii) pre-heated air (i.e. hot blast) which is passed through tuyeres near the bottom of the furnace.

2024年11月29日 · Blast Furnace Structure. The blast furnace uses steel plate as the shell, and the shell is lined with firebrick. The blast furnace body is divided into five parts from top to bottom: mouth, body, belly, bosh and hearth.

There are four major parts of blast furnace from bottom to top hearth, bosh, stack and top. The hearth acts as a storage region for molten metal and molten slag. The charge of blast furnace possesses successive layers of iron ore, scrap, coke, and limestone and some steel scrap which is fed from the top of the furnace.
